Miniature rose plant named ‘KORpagbel’

ABSTRACT

A new and distinct variety of miniature rose with long lasting, novel pink flowers, and dark green and attractive foliage. It exhibits compact, uniform growth and flowering under greenhouse conditions when grown as a potted floral plant. The new variety propagates well from cuttings and by grafting. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Genus, species and variety denomination: The botanical classification ofthe new rose plant is Rosa hybrida, var. ‘KORpagbel’.

BACKGROUND OF THE INVENTION

The new variety of miniature rose plant of the present inventionoriginated from a controlled crossing in a breeding program between‘KORnisecco’, a non-patented rose and ‘KORanalafi’ a non-patented rose.

The two parents were crossed and the resulting seeds were planted in acontrolled greenhouse environment. The resulting seedlings exhibiteddistinctive physical and biological characteristics. The new rose plantwas selected as a single plant from the seedling beds due to itssuperior characteristics for further evaluation. This new anddistinctive miniature rose variety is named ‘KORpagbel’.

SUMMARY OF THE INVENTION

The new rose plant may be distinguished from its seed parent, KORniseccoby the following combination of characteristics:

-   -   1. KORpagbel has light salmon-pink flowers while KORnisecco has        cream colored flowers,    -   2. KORpagbel has very double flowers while KORnisecco has only        double flowers; and    -   3. KORpagbel as a shelf life of 21 days while KORnisecco has a        shelf life of only 14 days.

The new rose plant may be distinguished from its pollen parent,KORanalafi by the following combination of characteristics:

-   -   1. KORpagbel has light salmon-pink flowers while KORanalafi has        salmon-orange flowers,    -   2. The flowers of KORpagbel have a diameter of 40-50 mm while        the flowers of KORanalafi have diameters of 30 mm,    -   3. KORpagbel has a better branching while KORanalafi has fewer        branches.

The objective of the hybridization was to create a new and distinct roseplant with unique qualities, such as:

-   -   1. Compact and uniform growth and flowering under greenhouse        conditions when grown as a potted floral plant;    -   2. Abundant, long lasting, and attractive flowers on upright        stems;    -   3. Resistance to diseases encountered in greenhouse and nursery        culture; and    -   4. Suitability for production from softwood cuttings in floral        and nursery containers;

This combination of qualities is not present in prior rose cultivars.These objectives have been substantially achieved and in thatdistinguish ‘KORpagbel’ from all other varieties of which we are aware.

As part of the rose development program, Tim-Hermann Kordes germinatedthe seeds from the aforementioned hybridization and conductedevaluations and observations on the resulting seedlings in a controlledenvironment in Offenseth-Sparrieshoop, Germany. The resulting seedlingsexhibited distinctive physical and biological characteristics. The newrose plant ‘KORpagbel’ was selected in May, 2001 from the seedling bedsand asexually propagated for further evaluation. The first asexualreproduction of ‘KORpagbel’ by softwood cuttings was in July, 2001 atthe Rosa-Danica Nursery in Odense, Denmark.

This initial and other subsequent propagations conducted in controlledenvironments show that the foregoing and all other characteristics of‘KORpagbel’ come true to form and are transmitted through succeedinggenerations.
